Objective: This 8-week, open-label trial assessed the efficacy of methylphenidate transdermal system (MTS) in 14 adult individuals diagnosed with ADHD and with a history of stimulant misuse, abuse, or dependence. Method: The primary efficacy endpoint was the Wender-Reimherr Adult ADHD Scale (WRAADS), and secondary efficacy endpoints included the Clinical Global Impression (CGI) ratings and substance abuse as quantified by urine drug screens and self-reported use. Results: Significant improvements from baseline were found on both the WRAADS and CGI measurements. No abuse of the study medication was observed. Conclusion: The findings suggested that MTS may improve ADHD symptoms in adults with a history of stimulant misuse; however, there were limitations. The study data showed the need for subsequent randomized studies that further explore findings made in this study.

A recently identified variant within the fat mass and obesity-associated ( FTO ) gene is carried by 46% of Western Europeans and is associated with an ~1.2 kg higher weight, on average, in adults and an ~1 cm greater waist circumference. With >1 billion overweight and 300 million obese persons worldwide, it is crucial to understand the implications of carrying this very common allele for the health of our aging population. FTO is highly expressed in the brain and elevated body mass index (BMI) is associated with brain atrophy, but it is unknown how the obesity-associated risk allele affects human brain structure. We therefore generated 3D maps of regional brain volume differences in 206 healthy elderly subjects scanned with MRI and genotyped as part of the Alzheimer's Disease Neuroimaging Initiative. We found a pattern of systematic brain volume deficits in carriers of the obesity-associated risk allele versus noncarriers. Relative to structure volumes in the mean template, FTO risk allele carriers versus noncarriers had an average brain volume difference of ~8% in the frontal lobes and 12% in the occipital lobes—these regions also showed significant volume deficits in subjects with higher BMI. These brain differences were not attributable to differences in cholesterol levels, hypertension, or the volume of white matter hyperintensities; which were not detectably higher in FTO risk allele carriers versus noncarriers. These brain maps reveal that a commonly carried susceptibility allele for obesity is associated with structural brain atrophy, with implications for the health of the elderly.

Background— Peripartum cardiomyopathy (PPCM) is a potentially life-threatening heart disease that occurs in previously healthy women. We identified prolactin, mainly its 16-kDa angiostatic and proapoptotic form, as a key factor in PPCM pathophysiology. Previous reports suggest that bromocriptine may have beneficial effects in women with acute onset of PPCM. Methods and Results— A prospective, single-center, randomized, open-label, proof-of-concept pilot study of women with newly diagnosed PPCM receiving standard care (PPCM-Std; n=10) versus standard care plus bromocriptine for 8 weeks (PPCM-Br, n=10) was conducted. Because mothers receiving bromocriptine could not breast-feed, the 6-month outcome of their children (n=21) was studied as a secondary end point. Blinded clinical, hemodynamic, and echocardiographic assessments were performed at baseline and 6 months after diagnosis. Cardiac magnetic resonance imaging was performed 4 to 6 weeks after diagnosis in PPCM-Br patients. There were no significant differences in baseline characteristics, including serum 16-kDa prolactin levels and cathepsin D activity, between the 2 study groups. PPCM-Br patients displayed greater recovery of left ventricular ejection fraction (27% to 58%; P =0.012) compared with PPCM-Std patients (27% to 36%) at 6 months. One patient in the PPCM-Br group died compared with 4 patients in the PPCM-Std group. Significantly fewer PPCM-Br patients (n=1, 10%) experienced the composite end point of poor outcome defined as death, New York Heart Association functional class III/IV, or left ventricular ejection fraction <35% at 6 months compared with the PPCM-Std patients (n=8, 80%; P =0.006). Cardiac magnetic resonance imaging revealed no intracavitary thrombi. Infants of mothers in both groups showed normal growth and survival. Conclusions— In this trial, the addition of bromocriptine to standard heart failure therapy appeared to improve left ventricular ejection fraction and a composite clinical outcome in women with acute severe PPCM, although the number of patients studied was small and the results cannot be considered definitive. Larger-scale multicenter and blinded studies are in progress to test this strategy more robustly.

Abstract Although levels of serum immunoreactive parathyroid hormone (iPTH) increase with age in women, this could be caused by retention of non-biologically active PTH fragments by the aging kidney. In 102 normal women, aged 30 to 89 yr, serum iPTH increased with age by 58% (r = 0.33, p &lt; 0.001) with antiserum GP-1M (which has midmolecule specificity) and 43% (r = 0.32, p &lt; 0.001) with antiserum CH-12M (which may have whole molecule specificity); urinary cAMP/GFR excretion increased by 29% (r = 0.22, p &lt; 0.05). The results of these assays were validated by comparison with serum levels of biologically active PTH (BioPTH) in immunoextracts of serum followed by renal adenylate cyclase assay in a selected subgroup of 25 of the women. Serum BioPTH correlated with serum iPTH assessed by antiserum GP-1M (r = 0.48, p &lt; 0.05) and antiserum CH-12M (r = 0.48, p &lt; 0.05) but not with urinary cAMP. The data are consistent with an increase of parathyroid function with aging: clearly, we do not find decreased parathyroid function as would be expected if age-related bone loss was not mediated, in part, by PTH.

We assessed adverse metabolic effects of atenolol and hydrochlorothiazide among hypertensive patients with and without abdominal obesity using data from a randomized, open-label study of hypertensive patients without evidence of cardiovascular disease or diabetes mellitus. Intervention included randomization to 25 mg of hydrochlorothiazide or 100 mg of atenolol monotherapy followed by their combination. Fasting glucose, insulin, triglycerides, high-density lipoprotein cholesterol, and uric acid levels were measured at baseline and after monotherapy and combination therapy. Outcomes included new occurrence of and predictors for new cases of glucose ≥100 mg/dL (impaired fasting glucose), triglyceride ≥150 mg/dL, high-density lipoprotein ≤40 mg/dL for men or ≤50 mg/dL for women, or new-onset diabetes mellitus according to the presence or absence of abdominal obesity. Abdominal obesity was present in 167 (58%) of 395 patients. Regardless of strategy, in those with abdominal obesity, 20% had impaired fasting glucose at baseline compared with 40% at the end of study ( P <0.0001). Proportion with triglycerides ≥150 mg/dL increased from 33% at baseline to 46% at the end of study ( P <0.01). New-onset diabetes mellitus occurred in 13 patients (6%) with and in 4 patients (2%) without abdominal obesity. Baseline levels of glucose, triglyceride, and high-density lipoprotein predicted adverse outcomes, and predictors for new-onset diabetes mellitus after monotherapy in those with abdominal obesity included hydrochlorothiazide strategy (odds ratio: 46.91 [95% CI: 2.55 to 862.40]), female sex (odds ratio: 31.37 [95% CI: 2.10 to 468.99]), and uric acid (odds ratio: 3.19 [95% CI: 1.35 to 7.52]). Development of adverse metabolic effect, including new-onset diabetes mellitus associated with short-term exposure to hydrochlorothiazide and atenolol was more common in those with abdominal obesity.

Purpose. Oral mucositis is a serious problem that affects a significant number of hematopoietic cell transplant (HCT) patients. There are many gaps in management, and evidence-based guidelines do not provide consistent recommendations. The purpose of this pilot study was to develop a mucositis oral care protocol for the prevention and management of mucositis in the HCT patient and to evaluate the clinical impact of its implementation. Methods. After receipt of Institutional Review Board approval, all patients admitted to the Hematology—Oncology service for high-dose chemotherapy followed by an autologous or allogeneic HCT were eligible for the study. As part of a change in practice, a new mucositis protocol consisting of a specific oral care regimen was instituted for prevention and treatment of mucositis. Assessment of mucositis began upon admission to the hospital and the patient was evaluated using a mucositis grading scale on a daily basis by the physician and nursing staff. The new mucositis protocol was a part of the HCT service admission orders for each patient. The group of patients treated according to the new mucositis protocol were compared with a retrospective control group consisting of patients who had undergone management of oral mucositis under the previous standard of care. The primary endpoints were to evaluate incidence, severity, and duration of oral mucositis. Secondary endpoints included days requiring narcotics; days of parenteral nutrition, febrile neutropenia, antimicrobial therapy, and length of hospital stay. Results. There were 13 patients enrolled in the control group and 12 patients in the new protocol group. The new protocol resulted in a decreased incidence (100% vs. 75%) and duration (19.2 vs. 8.3 days) of mucositis. Days of maximum grade one and three mucositis were decreased by 56%, and 70%, respectively. Days of maximum grade two mucositis, however increased by 22%. The days of narcotic use were reduced by 19% in the new protocol group (15.8 vs. 12.8 days). All patients in the new protocol group required parenteral nutrition, but days of use were reduced by 41% (17 vs. 10.2 days). The incidence of infection measured by days of febrile neutropenia and antimicrobial therapy were reduced by 35% (10.2 vs. 6.5 days) and 33% (17 vs. 11.4 days). Finally, the overall length of hospital stay was reduced by 7 days (30 vs. 23 days). Conclusion. Implementation of a standardized oral care protocol for mucositis management resulted in a decreased incidence, duration and severity of mucositis, and also reduced the global negative impact of mucositis. Future studies may further evaluate the global impact by adjusting for confounding factors. J Oncol Pharm Practice (2010) 16: 195—204.
